NeoMail stopped working

On a server NeoMail has stopped working (Horde is still working fine). Attempting to run /scripts/fixwebmail results in the following (below), and upgrading CPanel has not made any difference.

chown: failed to get attributes of `/usr/local/etc/cpanel/base/webmail/data': No such file or directory
chmod: failed to get attributes of `/usr/local/etc/cpanel/base/webmail/data': No such file or directory
